Abstract
An aerosol-generating article comprises an aerosol-cooling element. The aerosol-cooling element comprises an extruded member (100) having a length (108), and comprising an external surface (104) defining the perimeter of a cross section perpendicular to the length of the extruded member; and an internal surface (102) defining one or more pathways (110) through the length of the extruded member. The internal surface or the external surface or both the internal surface and the external surface comprise surface irregularities.

An aerosol-generating article comprising an aerosol-cooling element, wherein the aerosol-cooling element comprises:
- an extruded member formed from a polymer material;
- the extruded member having a length, and the extruded member comprising:
- an external surface defining the perimeter of a cross section perpendicular to the length of the extruded member;
- and
- an internal surface defining one or more pathways through the length of the extruded member;
- wherein the internal surface or the external surface or both the internal surface and the external surface comprise surface irregularities in the form of cracks or holes, that improve thermal transfer properties of the aerosol-cooling element with air.
A method of manufacturing an aerosol-cooling element of an aerosol-generating article, the method comprising:
- providing a polymer material;
- extruding the polymer material through a die to form a continuous extruded structure comprising an internal surface and an external surface, the internal surface defining one or more pathways within the continuous extruded structure and the external surface defining a perimeter of a cross section of the continuous extruded structure;
- inducing surface irregularities in the external surface or the internal surface or both the external surface and the internal surface, wherein the surface irregularities are in the form of cracks or holes that improve thermal transfer properties of the aerosol-cooling element with air;
- and
- cutting the continuous extruded structure to form the aerosol-cooling element.
